If you had a scale, you could weigh the object to determine its mass. (Note that mass is not the same as weight, but the two are closely related insofar as we use weight to determine mass.) You could then carefully submerge it completely in water to determine how much water it displaced. That would tell you its volume. You would then divide the mass by the volume to get its density.
But what if you don't have a scale? Can you still determine its density? I think you can.
Place a known quantity of water in a graduated container. Carefully place the object in the container and note the change in the water level. Subtract the new water level form the old. That is the amount of water displaced by the object, which should be floating since it's less dense than the water. The weight of the water displaced by the object is equal to the buoyant force pushing up on the object.
What does this tell us? Well, since the object floats, we know that the buoyant force is equal (but opposite) to the weight of the object. In other words, if we know the magnitude of the buoyant force, we know the object's weight (and therefore its mass)! Now, you can divide its mass by its volume, which you determined earlier by fully submerging it.
Here's another wayDetermine how much water is displaced by the floating object. Then carefully fully submerge the object and record how much water is displaced. If you divide the first number by the second, you will know its relative density compared to the density of water!If the floating object displaces 100 ml of water and the fully submerged object displaces 150 ml, then the relative density is 100/150 = 0.667. Since the density of water is 1.00 g/cm3, that means the density of the object is 0.667 g/cm3.
What else can I help you with?
Which planetis so light that it could float in water?
A planet's weight does not determine whether it can float in water. It's density is what determines that. Your question should be "Which planet's density is so small that it could float in water?"
Examples of solids that will float on water?
An example of a solid that floats on water is a needle, even though its density is greater than that of a water it still floats, this is because of Intermolecular Forces.Anything lighter (less dense) than water will float; this includes wood, some clothing, metal objects (like boats), provided they have enough air in between, etc.
Which planet has its density so low that it could float in water?
Saturn has a very low density and it would be able to float on water. The density of Saturn is: 0.687 grams per cubic centimeter.
What Solids that don't float on water?
one answer is a brick.A brick does not float on water.
Can coal float on water?
coal can float on water, because water's density is 1.0 g/cm3. and nothing is able to float on water unless it's density is less than water's density (; hope this helps you out! coal can float on water, because water's density is 1.0 g/cm3. and nothing is able to float on water unless it's density is less than water's density.
Can Saturn float in the water?
If you could find a body of water large enough to fit Saturn, yes it could float in the water. The density of Saturn is at 0.687 g/cm³.
What planet has a density so low tat it could float on water?
Saturn
Which gas giant could float on water?
Saturn, because it has a lower density than water.
Why is density needed to know whether a substance will float or sink in water?
It's actually pretty easy. If the density of the substance is higher than the density of water, the object will sink. If the density of the substance is lower than the density of water, the object will float. Be aware though that various substances may have dissolved into the water, thus changing its density. For example, seawater has a different density than fresh water.
What is the planet with an average density less then the density of water?
Saturn would float in water if you could find a big enough tub and the water to fill it.
What solid will float in water In which type of table could she find this information?
Any solid that is less dense than water will float in water. This information could be found in a density table. The density of water is 1 g / ml. One example of a solid that floats in water is ice, with a density of 0.92 g / ml.
If a matrial has a density of one will it float of sink in water?
If a material has a density of one, it will float in water. This is because the density of water is 1 g/cm³, so any material with a density equal to or less than that of water will float.
